We report a detailed investigation of the ${\mathrm{Ni}}_{2}\mathrm{Mn}\mathrm{Ga}$ shape memory alloy through magnetic, electronic, and thermal measurements. Our measurements anomalous Nernst effect (ANE) reveal that this technique is very sensitive to onset premartensitic transition in sharp contrast other transport With ANE being changes at Fermi surface, we infer on link between structural ...

In the last two decades, there has been an increasing interest in structural engineering control methods. Shape memory alloys and seismic isolation systems are examples of passive control systems that use of any one alone, effectively improve the seismic performance of the structure. Characteristics such as large strain range without any residual deformation, high damping capacity, excellent re...

are compared with the experimental results. In these test results the shape memory alloys behavior as: super elasticity under various temperatures, loading rate effects, asymmetry in tension and pressure, various loops of loading and unloading, hydrostatic pressure effects, different proportional tension-shear biaxial loading and unloading, and also deviation from normality due to non-proportio...

Smart composites, manufactured with embedded functional materials, hold the potential for a new type of structural health monitoring systems. The work herein focuses on how embedding Ni43Co7Mn39Sn11 metamagnetic shape memory alloy (MMSMA) sensory particles into pure aluminum matrix modifies chemical constitution and mechanical properties both materials. Martensitically transforming in Al or all...
